  • One-click access to extensive built-in data analysis routines
  • Advanced statistical analysis: Student's t-Test, ANOVA, chi-square test for variance, normality test (Shapiro-Wilk)
  • Linear and nonlinear curve fitting with weighting and estimation of statistical errors of the fit-parameters
  • Multi-peak fitting
  • Image analysis tools
  • Templates support: all settings for plots, tables and matrices can be saved and restored later on for a fast editing process
  • Project files based on folders, a powerful project explorer with built-in drag and drop and searching facilities
  • Full import of Excel workbooks and Open Document Format spreadsheets, dBase, SQLite and Microsoft Access databases
